Questions and Answers

Which of the following statements about the use of uricosuric agents like probenecid and sulfinpyrazone is correct?

  • They should not be used during an acute gout attack as they may precipitate an attack. (correct)
  • They do not interact with other drugs that are actively secreted by the renal tubules.
  • Aspirin and other salicylates can be used concomitantly to enhance the uricosuric effect.
  • They can be used alone for the treatment of chronic gout without the need for colchicine.

What is the primary side effect associated with the use of uricosuric agents like probenecid and sulfinpyrazone?

  • Urolithiasis (formation of urate stones) (correct)
  • Hepatotoxicity
  • Nephrotoxicity
  • Cardiovascular events

How do probenecid and allopurinol interact?

  • Probenecid and allopurinol have no clinically significant interactions.
  • Probenecid increases the half-life of allopurinol and enhances its uricosuric effect.
  • Allopurinol increases the clearance of probenecid, thereby reducing its uricosuric effect.
  • Probenecid decreases the clearance of allopurinol, thereby increasing dose requirements of allopurinol. (correct)
